At Berkshire Hathaway’s 2013 shareholders’ meeting, Warren Buffett said, “I’ve owned 400 to 500 companies’ stocks in my lifetime, but only about 10 of them made the most money.” His lifelong friend and investment partner, Charlie Munger, added, “With the exception of some of Berkshire Hathaway’s best investment practices, long-term performance is near-average.” Many people know Warren Buffett’s return on investment better than his mistakes or failures. It’s because of those 10 companies that he succeeded in investing. If there is a positive, there must be a negative. It’s better to prepare a realistic alternative in case you fail than to try to avoid failing. Humans are probabilistic beings. - Joseph’s “just my thoughts”
Since 2008, the US CDC has published annual flu reports aimed at preventing the spread of influenza nationwide. Researchers took two weeks to compile data on each flu outbreak by calculating the number of cases and generating a report. Meanwhile, the flu had already spread across the country. Google addressed this issue by analyzing search query statistics. However, an error emerged in 2013 when the flu vaccine became scarce, prompting the media to publish numerous flu-related articles that further distorted the situation by conflating the search terms for flu patients. In other words, accurate data analysis depends on the ability to interpret quality, untainted data and its context. - Joseph’s “just my thoughts”
